Dear syslog-ng users,
This is the 71st issue of syslog-ng Insider, a monthly newsletter that brings you syslog-ng-related news.
Version 3.19 of syslog-ng released
Version 3.19 of syslog-ng has been released with plenty of new features and bugfixes. Performance of the HTTP destination improved thanks to load-balancing to multiple servers. You can use this to send the messages to a set of ingestion nodes or indexers of your SIEM solution if a single node cannot handle the load. The new Slack destination allows you to send alerts to a Slack channel.

Optimize your Splunk infrastructure using new syslog-ng features
Learn how to use less resources for better performance in Splunk! Many people have been using syslog-ng for decades without knowing that it receives new features as well as bugfixes. While many Linux utilities are practically in maintenance mode, syslog-ng keeps evolving constantly. A strong focus in recent years has been on message parsing and destination drivers.
After my talk at Suricon, Splunk users explained how they will change their syslog-ng configurations to optimize their Splunk infrastructure.
Python source in syslog-ng
Using syslog-ng 3.18 and newer releases, you can write new source drivers for syslog-ng in Python. While performance is not as good as C, you gain flexibility and ease of implementation. There are quite a few log sources without a ready to use C API, but with a Python API. Using the Python source of syslog-ng you can leverage these.
